i have 225/35/19 and 255/30/19 I have a pair side cutters, tire plugs and compressor but have driven on deflated tires twice just to give them a true test both over the 50miles and once above 50mph the deflated tires felt solid and safe with no awful noises like stated. First bmw states minimum of 50miles can be up to 150miles depending on vehicle and cargo. Next Bridgestone, Michelin, Pirelli and continental all make run flats and non run flats in the same models
Pzero, ps2, reo50a And contisportcontact3 all come in both run flat and non so I think it make more sense comparing price and weight with same size make and model not comparing a run flat with a Michilen non Michilen makes some of the lightest tires in the industry
Conti sport contact 3 non and run flat are only about 30-40 dollars a tire different were the re050a might be closer to 80 and the new P7's are probably the furthest apart at 150 per tire from a run flat to a non but you need to compare apples to apples not to oranges
